|
| Adaptation 1: | Has microvilli - these create a larger surface area which help for a more rapid absorption |
| Adaptation 2: | Thin surface layer - this helps to create a short diffusion pathway so the small soluble molecules can diffuse into the villi quicker and more efficiently |
| Adaptation 3: | Good blood supply via capillary network - this allows soluble material to be transported away very quickly maintaining a concentration gradient |
